can add more more MD1200. But if I loose one MD1200
for any reason I lost the entire pool.
In your experience what's the «limit» ? 100 disk ?
How FreeBSD manage 100 disk ? /dev/da100 ?
Regards.

I've create a zpool with 4 raidz2 (one for each MD1200).
After that I re-install the server (I put some wrong swap size), and I
don't find my zpool at all.
Is that normal ?
Regards.

opinion the minimum ram
I need ? Is something like 48 Go is enough ?
Just make sure do NOT use dedup untul you REALLY know what you're
doing (which usually means buying lots of RAM and SSD for L2ARC).
Ok.

When we buy a MD1200 we need a RAID PERC H800 card on the server so we have

vdev uses 6-way
raidz
I can force this with «-f» option.
But what's that mean (sorry if the question is stupid).
What's kind of pool you use with 46 disk ? (46=2*23 and 23 is prime number
that's mean I can make raidz with 6 or 7 or any number of disk).
Regards.

Depending on needs for space vs. performance, I'd probably pixk eithr 5*9
) what you use to attach two 2disks on 2
different site ? You using FC attachement ?

The purpose is make a big NFS server with primary data on a high-level raid
array disk but using ZFS to mirror all data on the all old-raid-array.
